unfortunately there are no records in US that account for these cars far as production numbers w regards to transmission choices. Only the 442' s and their specific drive trains were accounted for . But sounds like a neat car

I only have production figures for 442's although I believe that others may have them for Cutlass'. The factory 4 speed Supremesare really rare. Do you have any documentation with the car? A lot of those options could have been added by previous owners. Do you have a pic of it? Where did you find it? I've been looking for a Supreme or Cutlass S 4 speed too. BTW The base trans for the V8 442 or Cutlasswas the 3 speed Ford Toploader. The 4 speed would have been an option too

I live just west of Syracuse. I never remember seeing it on Craigslist. Actually the factory cut the hole for the shifter with a torch and then tack welded the hump. The console brackets are reproduced. There should be three brackets. Here's a pic of an original floorImage title

The "rock crusher" is the name typically given to the M22 which didn't come out in Oldsmobiles until 1971. You probably have an M20 or M21. If you knew the rear end ratio you could really narrow it down. I think in 68 the only rear that was available in both the M20 & the M21 was the 3.42. The M20 was used in rears with ratios numericallylower than than 3.42 and M21's were used in rearsthat are numerical higher.

if your tranny is an m-22 it is unfortunately not original to car. As Mike said more than likely an M-20 assuming ratio is 342 or higher. If you give me more numbers off tranny can tell you, also look at tranny vin number on driver side . Should start w 38 then a letter and remaining 6 digits to match vin of car.

The Muncie M20 was the standard tranny for 3.08 gears on both the 2bbl & 4 bbl 350 Supremes in 68. If you don't have an assembly manual yet you should pick one up. It's a great resource.
